VOLVO DD25B ASPHALT COMPACTOR Service and Repair Manual

DD25B 2.6 t 25 hp VOLVO DOUBLE DRUM COMPACTORS

PERFORMANCE YOU CAN COUNT ON. 360° visibility With an optimally positioned sliding seat, angled drum mounts and a sloping hood design, the DD25B provides industry-leading, all-around visibility. Whether rolling forwards or in reverse, the operator has a clear view of the drum edges and surroundings – delivering precise compaction and improved safety.

3 Introducing the DD25B, a highly efficient double drum compactor designed to increase performance and reduce fuel consumption on small scale compaction projects. Featuring the new Volvo D1.7A engine, this machine meets the strict Stage IV/ Tier 4 Final emissions regulations without adding an exhaust after-treatment system. Experience increased machine performance and enhanced productivity with Volvo. High performance With Volvo’s high frequency compaction, the DD25B can travel faster while still maintaining the correct impact spacing necessary for high productivity and a smooth finish. The frequency can be adjusted from 3,300 vpm to 4,000 vpm to cater for different applications. Pressurized water system The DD25B boasts an industry-leading water tank capacity. A rust-proof, pressurized water system provides consistent flow to the front and rear drum surfaces – eliminating asphalt pick-up. Fine filters behind each of the eight spray nozzles minimize clogging and ensure correct fan spray coverage – providing ideal wetting of the drum surface. Reduced fuel consumption The Volvo D1.7A engine is perfectly matched to the DD25B’s hydraulic system – delivering high performance and a 7% reduction in fuel consumption. Optimized for efficiency The new Volvo D1.7A (18.5 kW/25 hp) engine effectively meets the stringent Stage IV/ Tier 4 Final emissions regulations without the cost or complexity of an exhaust after-treatment system. The optimized eccentric system ensures a powerful performance – equivalent to machines fitted with a bigger engine.

4 THE VOLVO EXPERIENCE. Urethane drum wipers Front and rear drum wipers are made of urethane – increasing effectiveness and component lifetime as well as reducing maintenance requirements. Engine compartment For easy maintenance access, the hinged engine hood tilts forward – providing wide access to the engine and hydraulic components at ground level. Water level indicator The operator can easily monitor the water tank level from the seat. Intermittent water spray The DD25B boasts an industry-leading water tank capacity. The operator can adjust the time between water sprays to the drums to conserve water and reduce refilling downtime. Auto start vibration Vibration engages automatically when the FSR lever is moved out of neutral and disengages when the lever is put in the stop position. This eliminates the risk of accidental damage to the mat. Optimized for efficiency The new Volvo D1.7A engine delivers high performance while meeting the stringent Stage IV/ Tier 4 Final emissions regulations without an exhaust after-treatment system. Reduced fuel consumption The Volvo D1.7A engine is perfectly matched to the DD25B’s hydraulic system – delivering high performance and a 7% reduction in fuel consumption.

5 Quick removal of nozzles Water nozzles can be quickly removed without the need for tools – increasing machine uptime and water system performance. Machined drums Machined drums with chamfered edges are perfectly round in order to produce a smooth, mark-free mat. High performance With Volvo’s high frequency compaction, the DD25B can travel faster while still maintaining the correct impact spacing necessary for high productivity and a smooth finish. 360° visibility With an optimally positioned sliding seat and a sloping engine hood design, the operator will experience industry-leading, all-around visibility. Maintenance-free bearings Maintenance-free eccentric bearings are lubricated for life and built to tolerate high temperatures and rotation speeds. Pressurized water system A rust-proof, pressurized water system provides consistent flow to the drum surfaces – eliminating asphalt pick-up.

6 Maintain your productivity. Easy-access engine compartment The engine hood can be easily opened for daily maintenance and inspection. The hinged engine hood design is lightweight and tilts forward with the aid of two gas struts giving wide access to the engine and hydraulic components.
